Overview
The B48's factory Downpipe includes a small-cell pre-catalyst that restricts post-turbo flow. This high-flow catted Downpipe replaces it with a less restrictive catalyst, improving turbo spool and exhaust flow on B48 applications.
- High-flow catalyst significantly less restrictive than the factory pre-cat or OPF
- Improved exhaust flow and turbo response versus the OEM Downpipe
- Retains catalytic converter — better suited to road-registered vehicles
- Stainless Steel construction for durability
Engineering Focus
SS304 Stainless Steel construction with a high-flow catalyst replacing the OEM pre-cat. Wide B48 platform fitment across F and G-series chassis.
Driving Experience
This kit clears it without giving up the catalyst, so the car stays road-legal and gains the turbo response the B48 has been holding back across the platform.

Built for the Drive, Not Just the Dyno
The factory B48 downpipe is sized to pass certification, not to flow freely — it's the first real restriction the exhaust gases meet after the turbo. This kit clears it without giving up the catalyst, so the car stays road-legal and gains the turbo response the B48 has been holding back across the platform.
